Simple Signs Your Furnace Needs Repair

A well-functioning furnace is essential for keeping your home warm and comfortable, especially during colder months.


However, furnaces can develop issues over time, leading to inefficiencies or even breakdowns.


Recognizing the signs that your furnace needs repair can help you avoid costly replacements and ensure your home stays warm.


Here are some common indicators that your furnace may need professional attention.


1) Unusual Noises


If your furnace starts making strange noises, such as banging, rattling, whistling, or screeching, it could be a sign of mechanical issues, loose components, or airflow problems.


Any unusual sounds should be inspected before they turn into serious repairs.


2 Weak or Uneven Heating


If some rooms in your home are colder than others or your furnace isn’t producing enough heat, it may be struggling due to clogged filters, ductwork issues, or a failing blower motor.


Inconsistent heating is a clear sign that your system needs maintenance.


3) Increased Energy Bills


A sudden spike in your energy bill without an obvious reason could indicate your furnace is working harder than usual.


This inefficiency may be due to a dirty filter, aging components, or failing parts that need repair or replacement.


4) Frequent Cycling


If your furnace is turning on and off frequently, it could be a sign of a malfunctioning thermostat, clogged filter, or improper airflow.


Short cycling puts stress on the system and reduces its lifespan, making prompt repair essential.


5) Strange Odors


A burning or musty smell when your furnace runs could mean dust buildup, electrical issues, or even mold in the system.


A persistent rotten egg odor could indicate a gas leak, which is an emergency requiring immediate attention.


6) Pilot Light Issues


For gas furnaces, a healthy pilot light should burn blue.


If it’s yellow, orange, or flickering, this may signal carbon monoxide issues or incomplete combustion.


Any changes in your furnace’s flame color should be inspected right away.


7) Poor Air Quality


If you notice an increase in dust, dry air, or allergy symptoms in your home, your furnace’s filter or ventilation system may be struggling.


Regular filter changes and maintenance can improve air quality and furnace efficiency.


Don’t Ignore Furnace Warning Signs


If you notice any of these signs, it’s best to schedule a professional inspection before small problems turn into costly repairs.


Regular maintenance and timely repairs will keep your furnace running efficiently and ensure your home stays comfortable all season long.

Twintech promptly responded to request for quotation. They were thorough and helpful in explaining options. The quote was very competitive. Installation of new furnace was very professionally completed. Excellent work.

by Rita, Scarborough on Twintech Heating and Cooling

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

by Bob S, Pickering on Twintech Heating and Cooling

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job we’ve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

The team was great! Very knowledgeable, professional and extremely helpful.

I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

by Rob on Twintech Heating and Cooling

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.

by Linda Robinson on Twintech Heating and Cooling

Timely and appreciated - this was during the hottest days this year when our Air and Furnace way.
Efficient. Professional. No BS or overselling. What was promised, was delivered at a cost-effective price point.
Down to earth.

by DG Sellers on Twintech Heating and Cooling

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.

by Bill, Pickering on Twintech Heating and Cooling

Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.
